**Abstract**
 A blend of LDPE and SBS was used to modify an asphalt, and a storage-stable modified asphalt was prepared by dynamic vulcanisation. The vulcanisation characteristics of the modified asphalt were studied using a strain-controlled rheometer. The vulcanisation of the SBS in the blend-modified asphalt resulted in a marked increase in the torque. The physical properties of the LDPE/SBS blend-modified asphalt containing even a small amount of sulphur were shown to be improved, together with its storage stability. The rheological properties of the blend-modified asphalt before and after the addition of sulphur were characterised using a dynamic shear rheometer and a rotational viscometer. 18 refs.
